Oscillators Procurement Notes

Verify the specific supply voltage requirement against the target circuit design, as variants exist with different voltage ratings. Confirm the package type matches the PCB footprint requirements. Ensure the enable pin configuration aligns with the system control logic to manage power states effectively during operation.

Oscillators Selection Notes

Select this component when a stable 14.3456 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V operating voltage constraint and the need for active enable control. The small form factor makes it appropriate for space-constrained designs where standard SMD mounting is preferred over through-hole alternatives.

Oscillators Part Context

This part belongs to the Quickie 8613 series of oscillators from Mercury Electronic. The manufacturer specializes in quartz crystals and frequency control products. This specific model represents a standard XO variant designed for general-purpose timing applications within consumer and industrial electronics sectors.

Oscillators Replacement Considerations

Direct substitutes include other 14.3456 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify electrical parameters such as load capacitance and drive level before substitution. Ensure the replacement part supports the same enable/disable control mechanism if power management is critical.
